I lost wieght and felt as if a big gap was in my life.

I had always been very healthy with rarely a cold before I quit. Developed severe migraine headaches a few months after quitting and was sick with colds 4 times.

After resuming a smoking life again, I felt better, ate more, have rarely been sick, and migraines are less.

I would like to quit and have slowly cut down. If I stop altogether I have a very bad migraine for days.

My father was a smoker. Is there a possibility of mutated genes passed on, that make me feel and function better with nictotine in my system?
